Code Description

ICD-10 S42.221 is a billable code used to indicate a diagnosis of 2-part displaced fracture of surgical neck of right humerus.

Key Diagnostic Point:

A 2-part displaced fracture of the surgical neck of the right humerus typically occurs due to trauma, such as a fall or direct impact to the shoulder. This type of fracture is characterized by a break in the bone that results in two separate fragments, which are not aligned properly. The surgical neck is located just below the head of the humerus and is a common site for fractures, especially in older adults due to osteoporosis. Symptoms include severe pain, swelling, and limited range of motion in the shoulder. Diagnosis is confirmed through imaging studies, such as X-rays or CT scans, which reveal the fracture's displacement and alignment. Treatment often involves orthopedic intervention, which may include immobilization with a sling or surgical repair, depending on the severity of the displacement and the patient's overall health. Surgical options may include open reduction and internal fixation (ORIF) to realign the bone fragments and stabilize the fracture. Rehabilitation is crucial for restoring function and strength to the shoulder post-injury.

Frequently Asked Questions

What is the difference between a displaced and non-displaced fracture?

A displaced fracture means the bone fragments are not aligned, while a non-displaced fracture means the bone remains in its normal position despite the break.
